so im trying to light my newly acquired lamp, the twin mantle dual fuel jobbie. i followed the destructions, burnt in the mantles with a match, filled it up with about 500ml of fuel, 30 pumps on the pump, turn to full and put match to mantles, it then lights and goes out, if i hold the match in then it pulses as in it flames up then goes out repeatedly.

anyone got any idea what im doing wrong?

You're getting the idea now. The more fuel, the less pumps. The stated 30 on the instructions is for a completely full tank. I usually pump at least 100.

Be advised though; if you open the cap now to put more fuel in, you'll release the pressure and will have to start over again when you put the cap back on.

I pump mine about 50 times pre lighting and 20/30 times more just after it's going. Pulsing is a sign of low pressure.

Good luck they are awkward beauties but nothing beats them when they work.

Does the lamp have a circular trough beneath the mantle? If so, you need some spirit gel in there, which you light, this burns and heats up the mantle so that the fuel can take.
Hope this helps..


Ahrroooo !!

I had similar problems lighting one for the first time.

I filled the tank up fully, pumped 30 times. Then everyone at the naughty corner said "do another 30". I tried lighting. Got nowhere really. Then someone who knew something said 'just keep pumping until you can't pump any more in'

I did that and it lit first time. No explosions.

I recently acquired one of these lanterns myself.had a few teething issues too.the above advice is spot on.yer can't really put a spot on figure too the amount pumps cause it depends on how much fuel you've got in their.ive just been giving it enough till the pumps becomes hard too push then lighting it.if it starts too pulse then just give it another 10 blasts repeatedly till it stops. Yer might find a fresh tank of fuel helps.heres were I was goin wrong

I got mine the other day, although it didn't pulse it did need a proper pressurising before it would glow fully. I thought I done it right but clearly it needed a good thorough going over.

So, pump untill it gets too tough to do anymore!

We were maintaining a safe distance whilst you were doing it just in case though! :D

It only took a few more days before you found another way to injurer yourself, hey? :rolleyes:

Several of us have decided to get you a locking rubber knife so you can safely do butter carving! Ooo just like hot rubber through butter! ;) Once you prove yourself with that then we'll progress you onto marzipan and a wooden knife. We'll carve you the wooden knife!

Dual fuel lanterns are intended for unleaded petrol or coleman fuel - NOT ethanol. If you are lucky you will simply need to strip it down and let the ethanol evaporate off.

Alternatively there may be replacement parts in your future.
